Gunalchéesh to Aandeiyeen for pointing me to this article. Older article, but it lays it all out nicely.
Alaskan Native fishing and hunting has, until relatively recently, been governed solely by indigenous systems of unwritten customs, beliefs, and practices that ensured the survival of families and villages. These unwritten rules were generally effective from a conservation standpoint. Equally important, they dovetail the complex web of social, cultural, and economic activities and personal relationships that define Alaska Native societies. The more recent, formal regulations of the state and national governments have often tom apart this web of relationships. The effect is perhaps unintended because the purpose is not to infringe on subsistence practices, but to protect wild, renewable resources by imposing bag limits, seasons, and other scientifically routine methods. These artificial limitations, however, often clash with the hunting and fishing practices of Native people who generally perceive such limits as unnecessary.
